note 109705 added to language.pseudo-types

If you pass a string as the callback function (i.e., 2nd parm to preg_replace_callback()), then PHP will interpret it as a function's name in the current scope -- and Main::dada_cb is not a valid function name in any scope. If you want to specify a static method of a class as the callback (i.e., "Main::dada_cb"), then you must pass as 2nd parm to preg_replace_callback: array( 'Main', 'dada_cb') And, if you want to use as a callback some method of an instantiated object (i.e., $object->dada_cb), then you must pass as the 2nd parm to preg_replace_callback: array( $object, 'dada_cb' ) ---- Server IP: 69.147.83.197 Probable Submitter: 70.91.82.193 ---- Manual Page -- http://www.php.net/manual/en/language.pseudo-types.php Edit -- https://master.php.net/note/edit/109705 Del: integrated -- https://master.php.net/note/delete/109705/integrated Del: useless -- https://master.php.net/note/delete/109705/useless Del: bad code -- https://master.php.net/note/delete/109705/bad+code Del: spam -- https://master.php.net/note/delete/109705/spam Del: non-english -- https://master.php.net/note/delete/109705/non-english Del: in docs -- https://master.php.net/note/delete/109705/in+docs Del: other reasons-- https://master.php.net/note/delete/109705 Reject -- https://master.php.net/note/reject/109705 Search -- https://master.php.net/manage/user-notes.php
